Aaron "Hotch" Hotchner was a pivotal character in Criminal Minds, but the sudden disappearance of Thomas Gibson's FBI Unit Chief remains one of the series' most infamous moments. Given the original Behavioral Analysis Unit in Criminal Minds was composed of a mere five special agents, it's no secret that the acclaimed crime drama preferred to take a revolving-door approach to its ensemble cast. With each new character introduced, however, Hotch remained an invaluable anchor that kept the series grounded— until season 12, at least.
Despite his character being irreplaceable at the very foundation of the series, Thomas Gibson was written off before Criminal Minds' original 15-season run could conclude. Yet, within the overarching narrative, Hotch had a fairly justifiable reason to leave. After numerous dangerous unsubs stalked, threatened, and even killed his loved ones, Hotch eventually opted to leave the BAU and protect his son by entering the Witness Protection Program. Though his exit was still certainly abrupt, it made enough sense from a story standpoint. Nevertheless, the true story behind Thomas Gibson's departure remains a controversial low point in Criminal Minds' lengthy history.
Why Thomas Gibson Really Left Criminal Minds
Countless casual viewers were caught off-guard by Hotch's season 12 exit, but Criminal Minds fanatics had more than enough time to prepare themselves during the height of the controversy. Following an alleged physical altercation with an on-set writer-producer, Thomas Gibson was suspended from the Criminal Minds cast in 2016. Shortly thereafter, Gibson released a statement of regret, chalking the incident up to a case of extreme creative differences.
According to other crew members, however, the 2016 conflict was far from the first time Gibson had clashed with his colleagues. In an official statement regarding the suspension, it was noted that Gibson attended mandatory anger management counseling after a previous dispute with an assistant director (via Deadline). Consequently, his suspension seemed less like an out-of-the-blue decision and more like the result of a problematic pattern of behavior.
Similarly, many sources spoke out during his suspension, describing the actor as anger-prone and unpredictable. As a result, Gibson was ultimately asked to leave the show a few weeks after the inciting incident (via Variety). While Gibson's firing was likely necessary to safeguard the comfort and safety of his coworkers, Hotch leaving irrefutably disrupted the trajectory of the overall series. Thankfully, Criminal Minds survived losing its iconic Unit Chief, and the crime drama is still going strong nearly a decade later.
Could Thomas Gibson Return In Criminal Minds: Evolution?
Hotch going into Witness Protection put a definitive end to his FBI career in the original series, but there's always a chance he could return in the Paramount+ continuation (known as Criminal Minds: Evolution). Unlike some characters who were similarly written out of the series, Hotch was never killed off, meaning there's always a possibility that the former agent could show up, if only for a brief cameo. Spencer Reid actor Matthew Gray Gubler appeared in Criminal Minds: Evolution already, so the door is theoretically open.

Criminal Minds Season 19's Callback To The CBS Original Is A Reminder Of Why It Still Works
Criminal Minds season 19 featured a fun callback to the CBS run of the show, and a look back at the original is a great reminder of its staying power.
Even still, possibility and probability are two vastly different metrics. The public fallout Gibson had with both cast and crew members during the show's initial run means that it's incredibly unlikely Hotch will ever be added to Criminal Minds: Evolution. Considering no one involved has expressed interest in the idea of the character returning, even a guest star capacity feels unrealistic.
Criminal Minds: Evolution Proves The Franchise Doesn't Need Agent Hotchner
Luckily, the 2022 reboot has been wildly successful without Aaron Hotchner. Evolution includes major changes from CBS' Criminal Minds— like a few new main characters— but different doesn't necessarily mean bad. In fact, plenty of beloved characters from the original series are still running the BAU, like Emily Prentiss (Paget Brewster), Jennifer "JJ" Jareau (A.J. Cook), Penelope Garcia (Kirsten Vangsness), and David Rossi (Joe Mantegna).
Rossi and Prentiss have both taken up the mantle left behind by Hotch's exit, and the overall chemistry of the central team is better than ever. Longtime fans may wish to see the original chief one last time, but there's truly no need to disrupt the new normal of Criminal Minds: Evolution.
What Thomas Gibson Has Said About Being Fired From Criminal Minds
Almost immediately after his termination was confirmed, Thomas Gibson gave his side of the story. According to the former star, he took issue with a line added to the script of an episode he was meant to direct. When he approached Virgil Williams with his concerns, the writer-producer allegedly insisted he wouldn't change it.
Regarding the ubiquitous rumor that he had violently kicked Williams, Gibson explained that "[his] foot came up and tapped [Williams] on the leg" (via Us Weekly) rather than the act being malicious and intentional. Furthermore, Gibson implied the producer would have run into his leg anyway had he not moved.
Gibson reportedly apologized the very next day, but his attempts to make amends failed, as the cast mainstay said he went home after shooting and never returned to Criminal Minds again. Ultimately, the actor expressed remorse, saying:
I love Criminal Minds and have put my heart and soul into it for the last 12 years. I had hoped to see it through to the end, but that won’t be possible now. I would just like to say thank you to the writers, producers, actors, our amazing crew and, most importantly, the best fans that a show could ever hope to have.
Notably, while it seems Gibson regrets the events leading up to his firing, he expressly did not assign himself blame or admit the disagreement with Williams went beyond a few choice words and an accidental physical confrontation.
What Thomas Gibson Has Done Since Criminal Minds
Unsurprisingly, Gibson's career has been scarce since leaving Criminal Minds. Despite his pre-Hotchner roles including cult classics and a well-known Chuck Lorre sitcom from the 1990s (Dharma & Greg), Gibson has only appeared in a few projects since his 2016 dismissal.
In 2017, Gibson voiced Joseph in Axis, a film ironically directed by Criminal Minds co-star Aisha Tyler (Tara Lewis). Two years later, he portrayed Colonel Branson in Shadow Wolves (2019), though the project was met with overwhelmingly negative reviews. Since 2020, the actor has had no credited on-screen roles, though he has sporadically taken to video-sharing platform Cameo to interact with fans and even answer Criminal Minds-related questions.
Most recently, Thomas Gibson helped create The Writer's Bible, an upcoming film currently in post-production. No official release date has been confirmed, and little is known about the movie aside from the basic premise of the eponymous struggling writer sojourning to rural Texas.
Other Long-Running Shows That Dealt With Similar Firings
Criminal Minds losing Hotch felt like a monumental blow, but there is an absurdly long history of television shows writing off major characters due to behind-the-scenes tensions and conflicts. Likewise, plenty of protagonists and roles that were otherwise vital to the main storyline were abandoned due to on-set behavior that resulted in firings.
Lethal Weapon is arguably the most similar case, as Clayne Crawford was let go after a stunt gone wrong during an episode he directed fueled public controversy. Similarly, it's been speculated for years that Chevy Chase was fired from Community due to using racial slurs on-set and generally making the cast and crew uncomfortable. Granted, Pierce Hawthorne was never one of Community's best characters, but Chase's exit was anything but quiet.
Of course, Charlie Sheen's departure from Two and a Half Men was a full-blown debacle. The comedy series was one of the biggest shows on air at the time, but it was marred by scandal following Sheen's public tirade against those he worked with. The actor continued his diatribes for weeks until the show ultimately announced Sheen's firing.
Is Criminal Minds Still Releasing New Episodes?
Thomas Gibson leaving undeniably changed Criminal Minds forever, but the show didn't end with Hotch's last episode. The continuation is currently airing weekly installments each Thursday on Paramount+, and the talented cast and crew are making the most of the show's new lease on life— and enjoying the liberties of its TV-MA rating.
While the present is commendable, the future is even brighter. Criminal Minds season 20 has already been confirmed, and the series shows no signs of slowing down any time soon. There's no telling exactly how much gas is left in Criminal Minds' tank, but it has absolutely lived up to its new namesake and evolved beyond the days of Aaron Hotchner.
